'Mlsishsu' 1., Williamson, Edge water, 'N. J. ApplicationAugust- 1s, 1935',-serio1 nofaauo ,3 Claims.

By such arrangeof one or more sheets from the, stack. Such ment upon opening the hinder, the leaves freed openings afford attachment, of the leaves indisubstantially from interfriction with one another, vidually and as'a stack by insertion therethrough open flat, affording utilization of the whole of the tongue element I; as is illustrated at [5. 55

The free end ef such tongue may be locked in position by insertion, through one or more incised slits as at l6 and/or lBain that portion of the cover member opposing that from which the tongue is blanked orincisedr V For further securement of the free end of the tongue and to position it within the cover member, the free end of the tongue, after such insertio-n, within one slitg say [6, is alsd inserted through a secend slit" l6a, parallel to such first slit 5. Such procedure positions the end of the tongue wholly within the enclosing or cover member, and provides a neat and readyarrangement for accomplishing the purposes of the invention.

It is desirable to also lock the free end 'of the tongue after it has been thus lodgedand this may be accomplished in various ways.

' Such incised slit may haveian outline of artistic configuration, in embellishment of the assembly as a whole.

-,The free end of the tongue is locked preferabl girby providing the tongue element with a serrated or other non-rectilinear outline, see i8, Fig. l, at both of itslateral edges, ene of said edges to be engaged and locked within the incised slit we of the cover member, and-the other edges to engage and lock relative to; another slit provided'thereinafor that purpose as at l9,

If desired, the binder may have an outer cover left entire, thatis, Without blanking therefrom anyf'tongue element, the l ose leaves; being detachablypositioned, as above set forth within an enclosingmemberwhich maybe ofrh'etal or the like, from which enclosing me mber the herein described'tongueelement or elements areblanked,

one-form ofwhich is illustrated in Fig. 4. Such inner member 10, ii may be dimensioned less .than its cover'Zl.

Such inner 'member [0, H may be formed as a' -channel to constitute the backbone and to directly embrace the stacl of loose leaves; and is secured to the outer cever member by adhesive or by stapling, eyeletting, etc., as indicated at 22. r

Q It will be understood that in such arrangement the lesser dimensions fthe'inner member I0, I l are satisfied by providing sufficient material forthe formation of the tongue element and the incised slits l6 and "id, through which it is to be inserted, lodged and as previously described. The preferred form of loose in thedrawings, has its inner edge, see edge portion I 26, Figs. 1 andA, spaced ,fromthe inner face of thebacliboneofthe enclosing member'Hl, II, as byproviding the extensions l2c, encompassing eacli apertured slot [4, recess or the like, such spaced edge portion. lt2b be tween such extensions constituting the major part of the whole inneriedgejof each sheet,

whereby upon opening the binder, the friction of the leaves relative to one 'anotherat their stated inner edges is negligible as compared with the effect afforded by the stated spacing of the major edge portions [21) from the backboneeand when so opened from all portions of the enclosing memberlp, ll; 7 I l In the useof a serrated or other non-rectilinear outline, see 18, -Fig, l, forthe lateral edges of locked, similarly leafpas illustrated 7 each tongue element, say tongue element i3a,

thereof, and slit I9. 5

Whereas I have described my invention by reference to specific formsthereof, it will be understood that' many changes and modifications may be made without departing from the spirit of the invention. TI 7 1, claim: 7 i

In a binder fer a stack of loose leaves, a cover; element having a flexible leaf-engaging tongue integrally!- ext'ending therefrom, said tongue having serrated lateral edges; a pair of slits in said cover element spaced apart mutually and spaced baclcviardlyfrom the base of said tongue, the individual slits of said pair of slits and the base of 1 said tongue being substantially mntually aligned in parallelrelation, whereby the tip ofsaid tongue maybepassed through that individual slit which is proximate" its base, and' thereafter through the other individual slit of the pair of slitsin securing the stack of loose leaves within the 'cover element; and means provided in the coverelementj forengaging onelateral edge of thefree endof the tongue in maintaining the I serrations of the other lateral edge of the tongue in lo'ckedlrelation with one end of at least the said other individdal slit of the said pair of slits.

,2. Structure as recited in claim 1,whereinthe stated other individual slit' is longer than the individual slit which is proximate the base of the tengue and is slightly offset lengthwise from the latter, and wherein the stated means for engaging one lateral edge of the tongue is a 'substantially arcuate slit farther removed from the base of the tongue thanis the stated pair of slits andjextending at substantially right an'gles to thelengths of the individual slits of the latter,

the said substantially arcuate slit being offset in- Wardly from that end of said lojiiger individual slit which extends beyond'the other individual slitof the pair of slits, and, further, having its convexity directed inwardly.

3. In a binder fora stack of loose leaves, a

cover element having at least one flexible leaf-i engaging tongue extending therefrom, said tongue having serrated lateral edges; a slit adapted to receive said tongue after engagement with said stack of'loose leaves, said slit having a length greater than the width of said tongue; and means for forcing one' lateral edge of the tongue into locking engagement with one end of. the said slit, said means being adapted to engage theother lateral edge'of the tongue to maintain said tongue .in locked status relative to the stack .of loose leaves 7 r f MARSHALL LWILLIAMSON;
